Lung disease burden assessment by oscillometry in a systematically disadvantaged urban population experiencing homelessness or at-risk for homelessness in Ottawa, Canada from a prospective observational study

Table 3 Mean R5-20, Ax and X5 values based on individual symptoms

Mean oscillometry values are reported for R5–20, Ax and X5 based on the presence of individual symptoms. R5–20 is a measure of small airway resistance. Ax is a measure of the area under the reactance curve. X5 is a measure of airway elastance. The presence of cough was defined as the presence of a cough on most days in the absence of a cold. The presence of phlegm was defined as the production of phlegm on most days in the absence of a cold. The presence of wheeze was defined as the presence of a wheeze any time in the last 12 months. The presence of shortness of breath was defined as activity limitation due to shortness of breath. P values were generated using a two-tailed t-test. ^ap = 0.06; ^bp = 0.03; ^cp = 0.05; ^dp = 0.12; ^ep = 0.07; ^fp = 0.02; ^gp = 0.01; ^hp = 0.13; ⁱp = 0.42; ^jp = 0.16; ^kp = 0.15; ^lp = 0.40. n = 56.
